Denver, Colorado 1920's directories

Denver, Colorado 1920's directories

I am trying to determine if Cecil C. Gaisford was still in Denver, Colorado past 1923, so if anyone has access to the Denver directories I would appreciate it if you could tell me the year of the last one he is listed in.

Cecil and his wife Grace Florence (May) were in the 1920 census in Denver, but I have never found any 1930 census records for them, nor any death or obits. I last see a reference to him regarding a court case that said he traveled home to Tacoma, Washington from Denver to render assistance to his parents in 1923.
